Is a glacier called a rock?
No, a glacier is not called a rock. A glacier is a large mass of ice that moves slowly over land due to gravity. Rocks may be found within or on top of a glacier, but the glacier itself is made of ice.
What is the top part of a glacier called?
The top part of a glacier is called the "glacier head" or "glacier accumulation zone." This area is where snow accumulates and compacts to form ice, feeding the glacier as it flows downward. The glacier head is crucial for the glacier's overall mass and movement, as it is where new material is added.
What part of a glacier moves fastest when glacier moves by internal plastic flow?
The center or axis of a glacier generally moves the fastest when the glacier is moving by internal plastic flow. This is due to the greater pressure and thickness of ice at the center, causing it to flow more readily than the slower moving edges and margins of the glacier.
Three different types of crevasses?
Bergschrund: A crevasse that forms at the top of a glacier where it separates from the rock or ice below. Transverse crevasse: Formed perpendicular to the flow of the glacier, typically due to the glacier bending or encountering obstructions. Marginal crevasse: Found at the edges or margins of a glacier and are often caused by variations in stress and strain as the glacier moves.
What is the elevation at the top of Harvard Glacier?
70,092
Why does the top of a glacier move faster than the bottom?
The top of a glacier moves faster than the bottom because of the effects of gravity. As the glacier flows downhill, the ice at the top is able to slide over the layers beneath it, causing it to move quicker. This phenomenon is known as internal deformation.
What can create cirques on the sides of mountains?
A cirque is the top of a glacier valley.
What is large ice mass that moves slowly down a mountain across land is called?
It is a glacier. As more snow and ice is added at the top, in the mountains, so the extra weight helps to push the front of the glacier downhill.
What models the behavior of a solar prominence best?
a glacier melting slowly on a mountain top
What happens when the top layers of a glacier move faster then the bottom layers?
you are so stupid
How did the debris on top of the glacier how did get there?
The debris on top of a glacier, often referred to as "glacial till," accumulates through processes such as erosion and weathering of surrounding rock and soil. As glaciers move, they scrape the landscape, picking up and transporting this material. Additionally, debris can be deposited on the glacier's surface from rockfalls or landslides occurring on steep mountain slopes nearby. Over time, this debris becomes embedded in the glacier as it advances and retreats.
What are the top 5 largest glaciers?
Malaspina Glacier in Alaska is bigger than the state of Rhode Island. Not exactly. Ice caps and ice sheets are kinds of glacier, and the two existing ones are over 50,000 square km long. Which is equal to about 30000 square miles.
